[DML] Re: Discovered the root cause of my starting problem (I think)



Not so fast VR. When cold the car starts on the cold start valve. It
opens on a lot less pressure than the fuel injectors so it is working
before the fuel injectors to get the motor started. That gives the
pump a chance to get the pressure up enough to make the fuel injectors
work. If you are having trouble starting the car (when cold)
troubleshoot the cold start system. The fuel accumulator is supposed
to hold up "Rest Pressure" so the car will start easily when warm. It
gives the fuel pump a "head start" to getting the pressure up enough
to run the fuel injectors. The motor doesn't need the Rest Pressure
when cold, the cold start valve can work at much lower pressures. Go
back and see if the cold start system is working. Try pulling out the
cold start valve, stick it in a can, and crank the engine when cold.
You should see it squirt. You can do a lot of troubleshooting WITHOUT
the pressure gauge set-up. Where do you start you ask? My advice is to
always start in the fuel tank. Clean it out and inspect all the parts
inside. Then, since you have decided the fuel accumulator is bad,
replace it. Now you can start troubleshooting the fuel system.
